# Anchors (&name) and aliases (*name). An alias is a REFERENCE to the same node, not a copy:
# after loading, `jobs.build` and `jobs.test` may be the identical object, so mutating one
# mutates the other unless the loader deep-copies. Round-tripping usually loses the anchors
# entirely and writes the value out three times.
